I have seen simmilar old reports that have been fixt with the last version from core/ArchiveProcessing/Day.php.
But I have the newest version.


did you solve the problem?
I have the same Problem with Version 1.12.0.

Thank you

please update to latest 2.0-a from: Index of /
(requires PHP 5.3)
does it fix the problem?

Hi Ahmet,

I would like to have a look at that potential Bug. Could you please get in contact with me at

Peter (Piwik-Team)

Same problem here. Process output:

Peter, please, let me know if I can help with any other data.

@Damián this is fixed I think in 2.0 beta 301 Moved Permanently

Thanks Matt, but is 2.0 ready for Production environments? I read that 2.0 stable is planned for mid November. In the meantime, is there any workaround to get it work in 1.12?

Seems that reprocessing the date using CoreAdminHome.invalidateArchivedReport finally works.
